Abstract
In this paper, a method for designing a portable UV-Vis Spectrophotometer is introduced. A miniaturized dispersion system is developed based on Hamamatsu array detector S3904 - 1024Q and flat field concave holographic grating. In order to solve the contradiction between spectral width and energy-utilizing ratio of light source, multi-band optical fibers are employed, which one side of the multi-bands optical fiber is arranged to be rectangle as incidence slit. The touch screen is employed as input and output system of the spectrophotometer and the miniaturized fiber-optic UV - Vis light source is employed as light source. The research and testresults of prototypes show that the new spectrophotometer based on our new method is miniaturization in volume (190*170*100mm3), can realize multi-wavelength detection on-line, is easily handled (touch screen control) and the performance accords with the Chinese National Standard.
